I've got the TeleTone version of this set, it has a small crack in it though.
Someone's selling an empty case for one on eBay that I'd like to have but the price is way too high.

I've looked at the schematics for both version and the TeleTone seems to have been "Muntzed" in comparison to the Sears, it has a really bare bones chassis.
